Of our many jobs here at Android Police, one is to make our readers' lives easier when we can. With that in mind, here's a roundup of every known Android 5.1 OTA for every Nexus device that will be receiving it. As new ones become available, this post will be updated accordingly. Android 5.1 will be released to Nexus 4, 5, 6, 7 (2012 and 2013), 9, and 10. As I'm sure you've guessed, there will be plenty of files to be had.

We've heard a number of rumors about Google launching its own Mobile Virtual Network Operator (MVNO), codenamed Nova. According to reports, the service will source wireless service from Sprint and T-Mobile, but it will rely on Wi-Fi networks to bear most of the weight of both data and voice services (though VoIP). While the details of this plan still aren't clear, another piece of the puzzle just emerged that indicates Google is going to offer its own virtual private network (VPN) service, and it may be targeted specifically at Nova subscribers.

Google has made Android 5.1 official and that means Nexus updates. Factory images are starting to pop up on the developer page, so you can easily get your device back to stock no matter what unspeakable things you've done to it. Google hasn't push images for all devices yet, but so far we've got the Nexus 5, Nexus 7 2012 (WiFi), and the Nexus 10.

Snagging a Nexus 5 from the Play Store hasn't been the easiest thing since the Nexus 6's launch, with the affordable handset fluctuating in and out of stock. The red and white versions disappeared before the end of the year, while the black option soldiered on for people who consider the Nexus 6 too big, too expensive, or both.

Of our many jobs here at Android Police, one is to make our readers' lives easier when we can. With that in mind, here's a roundup of every known Nexus Lollipop OTA. As new ones become available, this post will be updated accordingly.

Lollipop will be released to Nexus 4, 5, 7 (2012 and 2013), and 10, plus bugfix OTAs to Nexus 6 and 9. As I'm sure you've guessed, there will be plenty of files to be had.

Google typically phases the previous generation Nexus out whenever a new model comes to replace it, but the Nexus 6 is a partially massive device that leaves plenty of reasons to prefer 2013's smaller option. Unfortunately, the device has faded in and out of stock since its successor arrived, leaving folks to hunt on eBay and elsewhere. But now the Nexus 5 is back in the Play Store in both 16GB and 32GB.

It was a little behind the 2014 Nexus devices, but the venerable Nexus 5 is getting its update to Android 5.0.1 today. Along with that, there's a full factory image so you can flash your beloved 5-inch Nexus back to stock. Joy.

We get excited about bugfix releases around these parts, even if they don't bring the kind of glossy user-facing changes that the big updates do. Android 5.0.1 hit AOSP early this month, and now it looks like the over-the-air update will be on its way to Nexus 5 owners before the end of today. Sprint and T-Mobile have both shared the news themselves.

If you are the proud owner of a white or red Nexus 5, cradle your baby extra close tonight. It's now an endangered species. Google has removed the red and white options from the Play Store. leaving only the black N5 for those who like the Nexus experience, but hate big phones.

It's not unusual to see slightly customized builds of Android rolling out to Nexus devices shortly after the release of a new version. It certainly happened a few times with KitKat, and it looks like Lollipop is on track to do the same. As the rush of factory images and OTAs roll out, AOSP is also receiving commits for the new device-specific builds; and Al Sutton was quick to put out changelogs for each version.
